abdf4a161a explicitly switch marksets for concurrent marking 
this has very noticeable impact in initial marking time; it also allows us
to get rid of the confusing ts monikers.

60dd97c7fc fix potential deadlock in View 
As pointed out by magik, it is possible to deadlock if the view callback performs
a blockstore operation while a Lock is pending.
This fixes the issue by optimistically tracking the reference before actually calling
the underlying View and limiting the scope of the lock.
